Poland is mostly flat but we have some mountains and rock climbing. I cannot describe all of them (~200), so just I write about best spots where you can do rock climbing. Lucky this locations are very close to big cities like Kraków, Katowice or Wrocław. In a different article, I write about mountaineering in Tatras (the highest polish mountains) - check if you want.

The Tatra Mountains are located between Poland and Slovakia. They are the smallest Alpine range in Europe, with their highest peak Gerlachovský štít reaching only 2655 m above sea-level. They offer a lot of exciting rock climbing opportunities in summertime, yet wintertime can offer even better climbing options. The heights of walls reach up to 900 meters, about 200 - 300 meters on average. Their altitude is usually 1800-2300 m, so you don't need acclimatization.
